The City of Mammoth Spring, Arkansas. Home to our Riverfront Property on the Spring River.

Beginning near the Missouri border in northcentral Arkansas, Mammoth Spring, Arkansas is a charming, historical town located on the Spring River. Mammoth Spring, Arkansas's largest spring and 10th largest spring in the world, flows nine million gallons hourly. Forming a 10-acre lake, it then flows south as the Spring River, a popular trout and float stream. Nestled in the wooded hills of the Ozark Mountains Mammoth Spring is truly a little piece of heaven! Beautiful, clear air and four gorgeous seasons make it a wonderful place to visit or live!

Mammoth Spring is the largest spring in Arkansas. It is located in Mammoth Spring State Park, a state park of Arkansas, in the extreme north-central part of the state at the town of Mammoth Spring. Rainfall in southern Missouri seeps into the water table and flows through a vast system of passages and cavities. These cavities form a main channel and the groundwater reaches the surface at the town of Mammoth Spring, Arkansas. The emerging water forms a 10 acre spring pool that drains over a high stone dam and forms the headwater of the Spring River. The spring generates a flow of almost 370 cubic feet per second. The water emerges at a constant 58 °F. The spring itself cannot be viewed at the Mammoth Spring site because its mouth is more than 70 ft below the surface of the great spring pool.

Local folklore claims that the spring first emerged when an Indian chief was digging the grave of his son who had been killed while searching for water during a severe drought. Legend holds that the massive spring will flow forever because the young Indian brave had died while searching for water.

Nine miles northwest of Mammoth Spring visitors can see a portion of the underground river that feeds the spring at a collapsed cave at a Missouri State Park called Grand Gulf State Park. The remains of the cave are now a 40 m (130 ft) deep chasm with a natural bridge over it. Dye tests have proven that the water flowing through the 40 m (130 ft) chasm at Grand Gulf emerges at Mammoth Spring.

The spring was used to power a grist-mill from the times of the earliest settlers. The Mammoth Spring Milling Company constructed a dam and a water-powered grist-mill just below the site. In 1925 the dam was purchased by the Arkansas-Missouri Power Company which constructed a hydroelectric plant at the dam. This plant supplied power to the surrounding area until 1972.

In 1957, Mammoth Spring State Park was established. Surrounding land claims could not be acquired until 1972, however. Prior to 1972, the Mammoth Spring Cattle Sales Barn was co-owned and ran by local entrepreneuer Bert Kenneth Bishop and his associate, roughly on the site of where the Welcome Center now stands. Local farmers would routinely come to the site to sell livestock and other wares, such as Howard Green, who sold home-made walking sticks. Following this period in history, the State legislature voted to condemn the land and join the plot to the state park.

The original Frisco Depot was restored in 1971 and now functions as a repository for artifacts and memorabilia related to the railroad and the spring area. The State Park provides a visitor's center, picnic areas, walking trails, and tour access to the dam and hydro plant.

The United States Fish and Wildlife Service maintains a fish hatchery near the spring.
